  9. help
  10. udhcpc6 is a DHCPv6 client
  11. config BUSYBOX_UDHCPD
  12. bool "udhcp server (udhcpd)"
  13. default y
  14. select BUSYBOX_PLATFORM_LINUX
  15. help
  16. udhcpd is a DHCP server geared primarily toward embedded systems,
  17. while striving to be fully functional and RFC compliant.
  18. config BUSYBOX_DHCPRELAY
  19. bool "dhcprelay"
  20. default y
  21. depends on BUSYBOX_UDHCPD
  22. help
  23. dhcprelay listens for dhcp requests on one or more interfaces
  24. and forwards these requests to a different interface or dhcp
  25. server.

  27. bool "Lease display utility (dumpleases)"
  28. default y
  29. depends on BUSYBOX_UDHCPD
  30. help
  31. dumpleases displays the leases written out by the udhcpd server.
  32. Lease times are stored in the file by time remaining in lease, or
  33. by the absolute time that it expires in seconds from epoch.
  34. config BUSYBOX_FEATURE_UDHCPD_WRITE_LEASES_EARLY
  35. bool "Rewrite the lease file at every new acknowledge"
  36. default y
  37. depends on BUSYBOX_UDHCPD
  38. help
  39. If selected, udhcpd will write a new file with leases every
  40. time a new lease has been accepted, thus eliminating the need
  41. to send SIGUSR1 for the initial writing or updating. Any timed
  42. rewriting remains undisturbed.
  43. config BUSYBOX_FEATURE_UDHCPD_BASE_IP_ON_MAC
  44. bool "Select IP address based on client MAC"
  45. default n
  46. depends on BUSYBOX_UDHCPD
  47. help
  48. If selected, udhcpd will base its selection of IP address to offer
  49. on the client's hardware address. Otherwise udhcpd uses the next
  50. consecutive free address.
  51. This reduces the frequency of IP address changes for clients
  52. which let their lease expire, and makes consecutive DHCPOFFERS
  53. for the same client to (almost always) contain the same
  54. IP address.
  55. config BUSYBOX_DHCPD_LEASES_FILE
  56. string "Absolute path to lease file"
  57. default "/var/lib/misc/udhcpd.leases"
  58. depends on BUSYBOX_UDHCPD
  59. help
  60. udhcpd stores addresses in a lease file. This is the absolute path
  61. of the file. Normally it is safe to leave it untouched.
  62. config BUSYBOX_UDHCPC
  63. bool "udhcp client (udhcpc)"
  64. default y
  65. select BUSYBOX_PLATFORM_LINUX
  66. help
  67. udhcpc is a DHCP client geared primarily toward embedded systems,
  68. while striving to be fully functional and RFC compliant.
  69. The udhcp client negotiates a lease with the DHCP server and
  70. runs a script when a lease is obtained or lost.
  71. config BUSYBOX_FEATURE_UDHCPC_ARPING
  72. bool "Verify that the offered address is free, using ARP ping"
  73. default y
  74. depends on BUSYBOX_UDHCPC
  75. help
  76. If selected, udhcpc will send ARP probes and make sure
  77. the offered address is really not in use by anyone. The client
  78. will DHCPDECLINE the offer if the address is in use,
  79. and restart the discover process.
  80. config BUSYBOX_FEATURE_UDHCP_PORT
  81. bool "Enable '-P port' option for udhcpd and udhcpc"
  82. default n
  83. depends on BUSYBOX_UDHCPD || BUSYBOX_UDHCPC
  84. help
  85. At the cost of ~300 bytes, enables -P port option.
  86. This feature is typically not needed.
  87. config BUSYBOX_UDHCP_DEBUG
  88. int "Maximum verbosity level for udhcp applets (0..9)"
  89. default 9
  90. range 0 9
  91. depends on BUSYBOX_UDHCPD || BUSYBOX_UDHCPC || BUSYBOX_DHCPRELAY
  92. help
  93. Verbosity can be increased with multiple -v options.
  94. This option controls how high it can be cranked up.
  95. Bigger values result in bigger code. Levels above 1
  96. are very verbose and useful for debugging only.
  97. config BUSYBOX_FEATURE_UDHCP_RFC3397
  98. bool "Support for RFC3397 domain search (experimental)"
  99. default y
  100. depends on BUSYBOX_UDHCPD || BUSYBOX_UDHCPC
  101. help
  102. If selected, both client and server will support passing of domain
  103. search lists via option 119, specified in RFC 3397,
  104. and SIP servers option 120, specified in RFC 3361.
  105. config BUSYBOX_FEATURE_UDHCP_8021Q

  107. default y
  108. depends on BUSYBOX_UDHCPD || BUSYBOX_UDHCPC
  109. help
  110. If selected, both client and server will support passing of VLAN
  111. ID and priority via options 132 and 133 as per 802.1Q.
  112. config BUSYBOX_UDHCPC_DEFAULT_SCRIPT
  113. string "Absolute path to config script"
  114. default "/usr/share/udhcpc/default.script"
  115. depends on BUSYBOX_UDHCPC
  116. help
  117. This script is called after udhcpc receives an answer. See
  118. examples/udhcp for a working example. Normally it is safe
  119. to leave this untouched.
  120. config BUSYBOX_UDHCPC_SLACK_FOR_BUGGY_SERVERS
  121. int "DHCP options slack buffer size"
  122. default 80
  123. range 0 924
  124. depends on BUSYBOX_UDHCPD || BUSYBOX_UDHCPC
  125. help
  126. Some buggy DHCP servers send DHCP offer packets with option
  127. field larger than we expect (which might also be considered a
  128. buffer overflow attempt). These packets are normally discarded.
  129. If circumstances beyond your control force you to support such
  130. servers, this may help. The upper limit (924) makes dhcpc accept
  131. even 1500 byte packets (maximum-sized ethernet packets).
  132. This option does not make dhcp[cd] emit non-standard
  133. sized packets.
  134. Known buggy DHCP servers:
  135. 3Com OfficeConnect Remote 812 ADSL Router:
  136. seems to confuse maximum allowed UDP packet size with
  137. maximum size of entire IP packet, and sends packets which are
  138. 28 bytes too large.
  139. Seednet (ISP) VDSL: sends packets 2 bytes too large.
